I've looked everywhere I just can't come up with anything. Not that the threads are gone they're just never was any. One says Ford and has an h stamp. The other doesn't say Ford but has a six or a nine. I've asked quite a few people about this help me out ! Thanks

They could be Metz, Mike

I believe they're a later production as in '25 - '27.

The one say Ford on it. Wonder if they just were never finished? What Steve said and replacement after that.

Interesting. The squareness of the area around the fourth cylinder port and clamp indicates it is a late production manifold. It doesn't look like the threads were ground off, so they could be unfinished castings? However, it appears they may have been run somewhat? Another possibility is that they may have been originally used for a non-automobile purpose. Ford did sell engines, either complete or short or long blocks only for uses as marine engines, combines or other farm equipment, tow-motors, air compressors and other industrial uses. Some of those may have used simple clamped pipes for the exhaust.

The manifold on the bottom in photo one is the same manifold as the one on the right in photo two. It looks like it was cast with extra thickness to accommodate threading on the outlet end, The other manifold appears much thinner on the outlet end (or are my eyes playing tricks on me). Weren't some pre-T Ford exhaust manifolds made without threads as the exhaust pipe fastened without one (or an I wrong, again).
